Currently one of the highest capacity consumer SATA SSD on the market, this SSD offers huge amount of capacity and high R/W which is limited by SATA 3 max bandwidth. However, 4TB SSD and bigger begin to offer lower GB per dollar (which equals lower value) than the lower capacity SSD in the market such as 2TB NVMe SSD (Intel 660p 2TB at $194-209). [Dec '19 ColdSpy]

There's nothing inherently wrong with it. It does what it's supposed to do, it's M.2. The reason I chose this at the time was because I trusted the manufacturing tolerances of Micron, and I thought that other brands were overrated. It saves space, because it can be mounted directly onto the motherboard, in one way or the other. Of course...If I had just waited a little longer I could have bought the new MX500 series SSD, but they don't have any M.2 format drives released yet and there isn't much of significant difference; which is a higher read speed of 560 MB/s and 5 year warranty. The 3 year warranty and read speed of 530 MB/s is just fine! [Dec '17 morahman7vn]
